I tried both Steam and GOG and the control scheme is not supported on the deck. I don't know if GOG needs to talk to the devs of this game to implement proper control support for gamepads and the Steam Deck, so it is a waste of money for those of us on steam deck looking for a DRM free option for this game. At least the steam deck has community layouts. GOG needs to keep in mind handheld PCs are growing and they needs to make sure the games sold on here can work on them, even the deck. So much for trying to see what this game is all about but I don't play games on a keyboard, I prefer game pads. GOG, strive for this goal.
